I just bought a Mymusix 1gb mp3 player yesterday. It's supposed to hold about 200 songs on it and right now I only have 28 songs on it. It will charge and my computer will read it, but when I go to add songs on it, it wont let me put any on. It says its the wrong format or something, but ive tried several songs that are the same format as the ones that are on it now. If it matters, I use Realplayer to manage my mp3 player.
